Second, to provide a tool having these advantages which is very easily manipulated for the various kinds of work for which it is adapted.

Objects relating to details and economies of the invention will appear from the description to follow. The invention is defined and pointed'out in the claims.

A preferred embodiment illustrated in the accompanying of the invention is drawing, in

Fig. 1 is a perspective view of a tool embodying my invention. V

Fig. 2 is a side elevatidnal view thereof showing two adaptations to other wrenches as an extension or auxiliary handle for wrenches shown by dotted lines. a

Fig. 3 is a fragmentary showing other adaptations to wrenches as an extension handle therefor, a wrench being indicated in three positions by dotted lines.

Fig. 4 is an enlarged sectional view on a line 4-4 of Fig. 2.

Fig. 5 is a fragmentary view partially in section illustrating the tool as used on a plug or as it would be used on an Allen type screw.

Fig. 6 is a fragmentaryview partially in section illustrating an adaptation to another form of plug or as the tool would be applied to a nut or the like.

Fig. 7 is a side elevatlonal view illustrating the tool as used for a bending tool.

The tool of my invention comprises a handle I having a head 2 integral therewith. The head is provided with forwardly diverging arms 3. Each arm is provided with opposed pairs of polygonal jaw members 4-4 and also with a central pair of such polygonal jaw members 55. The jaw members illustrated are hexagonal and that is a desirable shape. The jaw members are formed integrally with or otherwise fixedly secured by welding so that they become an integral part of the tool. Each jaw member is provided with an internal jaw socket 6, desirably of the serratedtype;

The several jaw members are of relatively side elevational view 4 {Claims (Cl. SL-1 21) graduated external diameter and their sockets are of relatively graduated internal diameter.

The handle is provided with an opening I at its tively short and outer end so that it may be hung up. The pairs of jaw members are so spaced that one of the jaws 8 of a'double jawwrench 9 may be engaged with one of the jaw members 4 or 5 in different angular relations as shown in Fig. 3. Thus engaged, the tool becomes an extension or auxiliary handle for the wrench 9.

It is desired to point out that there are many wrenches of this type in which the handle is relawhich do not provide sufficient leverage for properly tightening or loosening a nut. Also there are various other work conditions in which it would be desirable to use the wrench ll but where the space is not sufficient to receive the hand of the operator. With the tool of my invention properly engaged in the angular relation best suited for the particular condition, not only additional leverage is providedbut the auxiliary tool permits the wrench to be positioned and operated under conditions which would not otherwise permit its practical use.

There are other situations where it is desirable to engage one of the jaws 8 with one of the center jaw members 5 and fulcrumingly engage the handle of the wrench 9 with one of the arm jaw members 4. This provides for further adaptation to meet particular conditions and may be resorted to where it is desired to manipulate a wrench of this type, the jaws of which do not fit any of the jaw members of the tool.

A nut I0 is indicated by dotted lines in Fig. 2. In Fig. 2, I also illustrate by dotted lines an adjustable jaw wrench H, which wrenches com- I monly have jaws only at one end. For that kind of a wrench the tool is engaged with the handle by positioning the handle between one of the arm jaws and the central jaw. Pipe wrenches may also be engaged in the same manner as the wrench indicated at l I. 7

In all of these adaptations as an extension handle or auxiliary handle, my tool is of great advantage not only in the matter of increasing leverage but the engagement in different angular relations; and, in conditions where the space does not permit a grasp of the handle of the work engaging tool, is of'great practical importance. The provision of the internal sockets enables the engagement of nuts and other work such as the stems I2 of the plug indicated at [3. The jaw members may also be engaged with plugs l4 having jaw receiving sockets I5 or with the Allen type of screws.

My tool may also be used with bending rods, tubes and the like such as indicated at I6 and for that work, I preferably provide a collar I! which is engaged over one of the arm jaw members and around which the work is bent by engaging the work with one of the .central ,jaw members. This" collar is peripherally circular. Work can be bent without the collar but the collar lessens the likelihood of kinking. Certain types of work require a short, rather sharp angular bend and in such wo'rk the collar omitted and the work bent around the selected arm jaw member.

I have illustrated and described .various adap-- tations of my tool and it is-believedothers will be apparent from this disclosure to those skilled in the art and to users of the .tool, I have not w,

said jaws being spaced to permit their individual engagement with jaws of a wrench having jaws ateach end thereof in .selected zangular relation thereto to constitute an extension handle for the wrench so engaged, said spaced jaws being spaced relative to said intermediate jaw to permit the positioning of a tool handle between :them.-ito provideuan :angularly disposed auxiliary ha l V 3.-A '-wrench-'also adapted for use as an aux- .iliary hand-1e for-other wrenches or tools and attempted to illustrate various other adaptations and uses as I believe this disclosure will enable" those skilled in the art to embody or adapt my invention as ;may be desired.

,Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. A wrenchalso adapted for use lasan auxiliary handle for other wrenches or .tools andlcomprising a handle, ,spaced externally ,polygonal laterally projecting jaw members at one end -of the handle, and ,an externally polygonal laterally projecting jaw member disposed onvsaid handle inwardly from said jaws and intermediate thereof, said jawmembers being of relatively .graduated diameters whereby the jaw members may be engaged-directly with W0rk,-0r a jaw member may be individually engaged with ;the jaw of a. wrench having jaws at .each end thereof in selected angular relation to such wrench to-fprovide an auxiliary :handle therefor, 101' the intermediate jaw member may .be-engaged with the jaw of Va wrench with its handle in supported jaw members to provide an auxiliary handle for the wrench :so engaged, or ,the handle ofa .tool may be engaged between the intermediatejaw memberand one .of said spaced -jaw members to provide an auxiliary handle therefor.

2. A-tool ofthe character described comprising a handle spacedpol-ygonal laterally projecting jaw .members .at one .end lof ,said handle, ,and

.a mterally projecting polygonal jaw member .levering engagement with one vof .said spaced comprising a-handle and a head integral with the handleiand having forwardly diverging arms, laterally projecting jaw members at the outer ends of the arms, *and a jaw member projecting laterally from said head, said jaw members having polygonal relatively graduated internal jaw sockets whereby the jaw members may be engaged direc'tlyand externally with work.

4. A wrench also adapted for use as an auxiliary handle for .other wrenches or tools and comprising a handle anda head integral .with the handle and having forwardly diverging arms,

laterally projecting externally polygonal jaw members at the outer ends of the arms and .an externally polygonal jaw member projecting laterally from said head, said jaw members'be'ing of relatively graduated diameters.
